Adding Disks to a Disk Group

You can use the ADD clause of the ALTER DISKGROUP statement to add a disk or a failure group to a disk group. You can use the same syntax with the ALTER DISKGROUP statement that you use to add a disk or failure group with the CREATE DISKGROUP statement. For an example of the CREATE DISKGROUP SQL statement, refer to Example 4-1. After you add new disks, the new disks gradually begin to accommodate their share of the workload as rebalancing progresses.

Using SQL statements to add disks to a disk group is illustrated in "Using the ALTER DISKGROUP SQL Statement to Add Disks to a Disk Group ". You can also add disks to a disk group with ASMCA. Refer to "Managing Disk Groups with ASMCA".
